Cannot open source file "WifiClientSecure.h"

thecois · July 27, 2024, 4:11pm

I have a piece of code in VSCode using the Platform IO extension. It is being copied straight from the Arduino IDE where it worked.

#include <WiFi.h>
#include <WiFiClientSecure.h>

WiFiClientSecure wifiClient = WiFiClientSecure();

void setup()
{
  Serial.begin(115200);
}
void loop()
{
  delay(1000);
}

This code does not compile; the error shown is:

src/main.cpp:2:10: fatal error: WiFiClientSecure.h: No such file or directory

The platformio.ini contents are:

[env:esp32dev]
board = esp32dev
platform = https://github.com/Jason2866/platform-espressif32.git#Arduino/IDF5
framework = arduino

Is there a way to make the code above compile (while keeping the same platform.io)?

This should work normally, the Arduino-ESP32 3.x core has just renamed WiFiClientSecure.h to NetworkClientSecure.h (source), but, it still provides the old header for compatibility.

I would advise to just delete C:\Users\<user>\.platformio and restart VSCode to get a fresh copy of everything.

That did not work.
i.e. removing ~/.platformio and restarting VSCode yielded the same error
(I also tried using the new name NetworkClientSecure.h ; same result)

And when you set platform = espressif32?

thecois · July 27, 2024, 5:16pm

Same error is shown when setting platform = espressif32

My bad, platform = espressif32@6.7.0. (That would use Arduino-ESP 2.0.16)

thecois · July 27, 2024, 5:48pm

espressif32@6.7.0 does work

Thanks

Just keep in mind that this will use the older Arduino-ESP 2.x core, not 3.x. I’m not sure why platform = https://github.com/Jason2866/platform-espressif32.git#Arduino/IDF5 would not have that library… it should.

If you want to use Arduino Core 3.0.3 give pioarduino a try:

[env:esp32dev]
platform = https://github.com/pioarduino/platform-espressif32/releases/download/51.03.03/platform-espressif32.zip
board = esp32dev
framework = arduino

The compilation result of your main.cpp::

Let’s hope that the Espressif politics side of this issue is quickly resolved and we just get a regular espressif32 platform update to core 3.x. There are at least 3 different ways / platform forks now that one could use to get core 3.x, it’s really getting out of hand.
